Hello, I live by the freeway in the burbs of LA. My mindset was to always close the windows because of traffic smog. Since I got the AirGradient Indoor Monitor, keeping the windows would have a high CO2. If I open the windows, CO2 is good and oddly PMs are ok and so are the other parameters. Assuming this is a good thing and I can keep windows open within reason within the monitor readings? What have you all found in similar situations?
Thanks!
